Title: Metal oxide semiconductor type semiconductor integrated circuit
Inventor: SUDOU MASATOSHI
IPC: H01L21/76
Filed: 1981-10-02
Abstract: PURPOSE:To prevent the generation of a parasitic MOSFET by forming a semiconductor layer, which is electrically connected to a semiconductor substrate and to which fixed voltage is applied, between an electrode functioning as the gate electrode of the parasitic MOSFET and the silicon substrate section just under the electrode. CONSTITUTION:A fixed potential electrode 16 is formed into a field oxide film positioned onto the silicon substrate section 15, and the one part 16' is connected to the silicon substrate. According to such constitution, the generation of the parasitic MOSFET is prevented because the electrode 13 has no effect on the silicon substrate section 15. The width l1 of the fixed potential electrode 16 is not limited particularly, and may be equal to the width l2 of the silicon substrate section 15.

Title: Pneumatic tire and manufacture thereof
Inventor: IWATA TOYOMI
IPC: B29D30/72
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To effectively inhibit projections at the connecting part of a side and disturbance of a cord at a carcass layer at a connecting part-superposed site. SOLUTION: One end face 28 and the other end face 29 located in the peripheral direction and closely connected to each other in a side 23 are inclined to the outer surface of the side 23. The inclination B is gradually narrowed toward the outside in the radius direction from the inside in the radius direction. Thus the width (the connected area) of one end face and that of the other end face 28, 29 in the peripheral direction are gradually widened toward the outside in the radius direction. The result inhibits disconnection at the outer end of the side 23 in the radius direction to reduce the degree of overlapping in one end and the other end in the peripheral direction of the side 23.

Title: Series lighting device for discharge lamp
Inventor: INOUE YOSHINORI
IPC: H05B41/23
Filed: 1992-05-25
Abstract: PURPOSE:To perform a series lighting with a small power source capacity in a circuit in which a plurality of primary windings are connected in series to a power source, and discharge lamps are connected to secondary windings, by connecting a plurality of lighting capacitors different in capacitance to each primary winding or secondary winding. CONSTITUTION:Lighting capacitors 8a-8n different in capacitance are provided on both ends of secondary windings 6a-6n or primary windings 3a-3n. When a power source is applied, a discharge lamp connected to the secondary winding having a large apparent exciting impedance 2 is first lighted since the exciting impedance of each transformer is different from the parallel impedance with each capacitor or the apparent exciting impedance. When it is lighted, the voltage is reduced to a discharge keeping voltage, and the discharge lamp of the transformer having a large share of the power source voltage is started to discharge. Thus, the necessary power source voltage is significantly reduced, compared with the case of uniformly applying the voltage to each transformer 2a-2n to light discharge lamps, and the power source capacity is minimized.
